ANIMAL BEHAVIOR TERMS TO KNOW • Instinct – (reflexes and responses) what the animal has at birth. Ex. Nursing, searching for food. • Habituation – learning to respond without thinking, response to certain stimulus is established as a result of habituation. • Conditioning – learning to respond in a particular way to a stimulus as a result of reinforcement when the proper response is made. TERMS TO KNOW • Reinforcement – a reward for making the proper response. • Reasoning – the ability to respond correctly to a stimulus the first time that a new situation is presented. • Intelligence – the ability to learn to adjust successfully to certain situations. Both short-term and long-term memory are part of intelligence. MAJOR TYPES OF ANIMAL BEHAVIOR • Sexual • Eliminative • Maternal • Shelter-Seeking • Communicative • Investigative • Social • Allelomimetic • Feeding • Maladaptive SEXUAL BEHAVIOR Useful in implementing breeding programs Examples of Sexual Behavior o Cows that are in heat, allow themselves to be mounted by others o Bulls, rams and stallions smell the vagina and urine to detect pheromones o Flehmen – Male animal lifts head and curls its upper lip o Rams chase ewes that are coming into heat o Sows seek out boars for mating o Mares in heat squat and urinate when stallion approaches and vulva winks MATERNAL BEHAVIOR Females taking care of newborn and young animals Examples of Maternal Behavior o Mothers clean young by licking them o Mothers fight off intruders o Become aggressive in protecting they young after birth COMMUNICATIVE BEHAVIOR When some type of information is exchanged between individual animals Examples of Communicative Behavior o Distress Calls – Lambs bleat, calves bawl, pigs squeal and chicks chirp o Dams recognize offspring by smell o Farm animals respond to calls or whistles of the producer o Bulls bellow deeply to communicate aggressive behavior SOCIAL BEHAVIOR Includes “fight or flight” and aggressive and passive behaviors between animals Includes interactions with other animals, humans and behavior during handling and restraint Examples of Social Behavior o Males of all farm animals fight when they meet other unfamiliar males of the same species o Cows, sows and mares develop a pecking order, but fight less intensely than males o Cows withdraw from the herd to a secluded spot just before calving o Almost all animals withdraw from the herd if they are sick FEEDING BEHAVIOR Exhibited by animals when eating and drinking (Ingestive Behavior) Examples of Feeding Behavior o Cattle graze 4-9hrs/day, ruminate 4-9hrs/day, regurgitate 300-400 boluses of feed per day o Sheep and goats graze 9-11hrs/day, ruminate 710hrs/day, regurgitate 400-600 boluses of feed per day o Cattle usually don’t go more than 3 miles away from water o Sheep may travel as much as 8 miles a day ELIMINATIVE BEHAVIOR Elimination of feces and urine Examples of Eliminative Behavior o Cattle, sheep, horses, goats and chickens eliminate feces & urine indiscriminately o Hogs eliminate feces in definite areas of a pasture or pen o Cattle, sheep, goats and swine defecate while standing or walking, urinate while standing, but not walking o Cattle defecate 12-18 times/day, urinate 7-11 times/day o Horses defecate 5-12 times/day, urinate 7-11 times/day o Animals defecate & urinate more when stressed or excited o Animals loose 3% of their live weight when transported to & from market points (Shrink) SHELTER-SEEKING BEHAVIOR Examples of Shelter-Seeking Behavior o Animals crowd together in snow and cold winds o Animals seek shelter of trees when it rains o Cattle and sheep seek shady area for rest and rumination if weather is hot o Hogs find a wet area if weather is hot o In extreme situations, animals pile up to the extent that some get smothered INVESTIGATIVE BEHAVIOR Examples of Investigative Behavior o Pigs, horses and dairy goats are highly curious, investigate any strange object, approach carefully, slowly, sniffing and looking as they approach o Sheep are less curious and more timid ALLELOMIMETIC Animals of a species tend to do the same thing at the same time Important in that a producer may observe the herd with little difficulty, also useful in driving groups of animals from one place to another Examples of Allelomimetic Behavior o Cattle and sheep tend to graze at the same time and rest and ruminate at the same time o Range cattle gather at the watering place about the same time each day because one follows the other MALADAPTIVE BEHAVIOR Animals that cannot adapt to their environment, exhibit inappropriate or unusual behavior Examples of Maladaptive Behavior o Chickens and swine in extensive management (confinement) systems resort to cannibalism, removal of tails is a prevention method o Buller-steer syndrome – steers that have been castrated before puberty demonstrate masculine behavior
